In the provided context, a game engine is described as having expanded far beyond its original role as software for making games. Since the 2010s, it has increasingly functioned not only as a production tool but also as a critical object, a film studio, a simulator of autonomous worlds, and even a location or performance space. In media art and game art, the game engine is therefore treated less as a means of playing games and more as a flexible infrastructure for world-making: a system that generates, sustains, and makes operable computed worlds.
This shift also shows how game engines connect to fields such as film, architecture, AI, simulation, and virtual production. In Ian Cheng’s Emissaries, for example, a video game engine serves as the basis for live simulation, producing open-ended situations through interactions among characters, animals, and plants, without relying on direct audience control. In other cases mentioned in the context, such as Farocki, Lek, and Total Refusal, the game engine is repurposed for cinematic production, critique, or performance. As a result, the central question moves away from “Is game art art?” toward “By whose rules does a computed world exist, and who acts within it?” The source material does not provide a full technical definition of game engines.
